The correct option is A India and Japan
The center of origin is a geographical area, where a group of organisms, either domesticated or wild, first developed its distinctive properties. Centers of origin are also considered centers of diversity.
Rice is the seed of the grass species Oryza sativa (Asian rice) or Oryza glaberrima (African rice). As a cereal grain, it is the most widely consumed staple food for a large part of the world's human population, especially in Asia. It is the agricultural commodity with the third-highest worldwide production, after sugarcane and maize.
Rice or Oryza sativa is not a tropical plant but is still associated with a wet, humid climate. It is generally believed that the domestication of rice began somewhere in the Asian arc. From its place of birth, lost forever in the mists of time, the plant and its grain spread all over the world.
According to some schools of thought, It is probably a descendent of wild grass that was cultivated in the foothills of the Eastern Himalayas and the upper tracts of the Irrawady and Mekong river basins. Another school of thought believes that the rice plant may have originated in southern India and then spread to the north of the country.
From India, the plant spread to China and then onwards to Korea, the Philippines (about 2000 B.C.), Japan and Indonesia (about 1000 B.C.). The Persians are known to have been importers of this grain. From there its popularity spread to Mesopotamia and Turkestan.
